RE: M5Paper STL Files available?posted in PRODUCTS
@lwtsde said in M5Paper STL Files available?:
M5Paper
Hello!
It depends on the accuracy of the 3D Printer.
M5 Paper requires high accuracy.
You need a high-precision printer.
The accuracy of the printer for amateurs is about 0.4mm width.
I think it is impossible because the accuracy is low. -

RE: Atom Button at GPIO39 without Pullup?posted in Atom
Hello @Dieter_P
I don't own ATOM Lite (ESP32-PICO-D4), so I haven't checked it.
- Does the problem occur when using WiFi?
- You need to check the signal of GPIO39.
：
In M5Stack (ESP32-D0WDQ6-V3), there is a case where GPIO39 works without permission when using WiFi.
M5.BtnA.wasPressed() conflicts with WiFi
https://forum.m5stack.com/topic/3262/m5-btna-waspressed-conflicts-with-wifi
：Supplement：
Example of using GPIO39.
M5Stack Basic (ESP32-D0WDQ6-V3)：PULL UP with 100KΩ.
ATOM PSRAM (ESP32-V3-02)：PULL UP with 5.1KΩ.
M5Stamp Pico (ESP32-PICO-D4)：PULL UP with 5.1KΩ. -
